Jessa Duggar says she wants to have "many" more kids in the future.
"Ben and I still have a deep desire to adopt, and it's something we continue to look into," Duggar told the magazine. "We've also talked about fostering to adopt."
"[We want] many future babies," she said. "We're already going to have two babies in a two-bedroom house. So I'm thinking, we'll have to upgrade to a three-bedroom."
The 19 Kids & Counting alum is the third-eldest daughter of Jim Bob and Michelle Duggar, and grew up with 18 siblings.
"Kids are so important. We hope to adopt a lot of kids. If God blesses us with biological kids of our own, it's not going to quench our desire to adopt," the star said.
"Even before we were married, we wanted to adopt."
"We are overjoyed to announce that Spurgeon has a new title in life as 'big brother'!" the pair said at the time. "We are so thankful that God is adding to our family."
"2017 is shaping up to be a wonderful year already and we know Spurgeon will do a great job in his new role," they added.
"Having Spurgeon has been such a wonderful blessing and we cannot wait to see the face of this sweet new baby (or babies!)."
The "Counting On" star posted a video of the baby kicking in November, writing, "It's amazing!" Her sister, Jill Duggar, is also pregnant and expecting a baby boy with husband Derick Dillard.
